T 0 all whom it may concern:

Be it known that I, ALEXANDER P. WHITE, a citizen of the United States, residing at Caldwell, in the county of Essex and State of New Jersey, have invented. certain new and useful Improvements in Lathing Structures, of which the following is a specification. 4

This invention relates to a new and practical material for building purposes, and possessing special utility as lathing for forming walls, floors, partitions and other structural parts.

The primary object of the invention is to produce a building structure especially available for lathing, which has many ad vantages structurally, as well as commercially, over the ordinary wooden lathing, and over the plain metal lathing of the woven wire type.

To this end, the invention has in view a novel and practical combination of metal and non-metallic elements which not only overcome present objections, but at the same time effect a great saving in metal.

These general objects are better attained, according to the present invention, by utilizing a novel form of filler element which may be so distributed or located throughout the structure as to greatly reduce the quantity of metal employed, while at the same time partly closing the spaces between wires,

thus making a stiff base for plaster which can readily be covered without waste of plaster.

For convenience of description, I shall refer to the members formed with a core wrapped 0r enveloped with a fibrous sub stance, as fillers, though in addition to the function of partly filling the spaces between wires, they have also the function as wires in that they are the weft elements of the product. These filler members may be utilized as weft members in the woven fabric structure in any desired number and-arrangement, together with the ordinary wire weft and warp elements of the fabric, thereby rendering the improvement more readily available by reason of the adaptability thereof to be manufactured by simple and well known weaving processes.

With these and other objects in view which will more readily appear as the nature of the invention is better understood,

the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of I the invention is shown in the accompanying drawings, in which Figure l is a perspective view of a portion of my improved fabric.

Figure 2 is an enlarged cross-sectional view on the line 22 of Figure 1.

Figure 3 ilustrates a preliminary ste in one of the several ways in which the dller member of the fabric may be formed.

Figure 4'is a perspective view showing a preliminary state of one of the filler memers.

. Figures 5, 6, and 7 are more or less diagrammatic views illustrating a practical means for givin the ultimate shape and form of the filler elements shown inFigure 4.

Figure 8 is a cross sectional view showing a further means for making the fibrous filler elements.

Figures 9 and 10 are detail perspective together by any suitable process or machine,

and usually and preferably consolidated. in the same structure by the simple process of weaving. i

It is not the purpose of the present invention to be limited to'an particular manner ,of assembling or conso idating the several warp or weft members of the structure, nor to the number of metallic. and. composite members employed, but the idea of the present invention is to materially reduce the number of. wire elements employed and to have the filler members -predomina teoverthe superficies, thereby makin employ a comparatively sum the metallic members- Therefore, it will be understood that the .distinctive feature of .the present invention resides in the incorporation in the fabricated it po'ssibleto numberof structure of relatively wide filler members 3 marily it consists of a fibrous body portion 4, and a central vertebrae strip or rib 5, the latter being preferably a wire or bar of relatively thin gauge, which is utilized as a core about which to build the fibrous body. By reason of the large area presented y the surface of the filler members the latter will necessarily occupy a very large proportion of the total area of the fabric, thereby reducing the number of metallic parts, and at the same time affording a large area of frictional contact for engagement with the wire elements, as distinguished from a mere oint of contact between the wire elements t emselves, thus greatly stiffening the structure. When plaster is applied to an all wire product used as lathing, there is a tendency for the plaster to out through the meshes, but in my improved material, the wide surface of the filler members prevents this.

In the formation of the filler member or unit 3, it will be-understood that the fibrous body 4 thereof may be made in any suitable manner, and of fibrous material in bulk or sheet formation, and the vertebraecore or strip 5 inserted or consolidated therewith in any manner best adapted to conditions and requirements, but for the purpose of illustrating one way of commercially manufacturing this filler or unit, there is shown in the drawings a means for making the same from fibrous material, such as paper, which is preferably treated with an emulsion of silicate of soda and liquid asphalt. This emulsion renders the material substantially water and fire-proof, as well'as stifl'ening the same. Besides wrapping the wires with a paper, there may also be provided a suitable substance such as plastic cement to form a part of the composite structure built about the wire core, as illustrated in Figures 3 and 4.

Beferrin now to the illustration of one manner of %orming the fibrous filler members or units 3, it will be observed from Figure 4 of the drawings that the metallic vertebrae strip 5 may be utilized as the ori inal core upon which is wound and deve oped the fibrous body portion 4. That is to say, according to this method of manufacture, the metallic strip, wire or rod 5 may be the core upon which, by suitable machinery, is loosely wrapped the co'nvolutions of a paper sheet or blank S, resulting in a preliminary unit of the general character shown in Figure 4 of the drawin s, wherein the core 5 is completely encase and surrounded by the loose convolutions of the paper S. Either before or after being treated with an emulsion of the character referred to, the said preliminary unit, preferably while moist and plastic from theemulsion, is subjected to a rolling .or pressing operation which will squeeze and flatten the same into its ultimate cross-sectional form shown in Figure 2 of the drawm s. fihis operation may be performed in any way or by any suitable mechanism, but may be conveniently accomplished in the passes of a series of reducing rolls, as suggested in Figures 5, 6, and 7. In these figures of the drawings, the reducing and flattening rolls are designated respectlvely by the reference numerals A and B, and are separated sufiiciently to provide the substantially horizontal flattening passes C to form and reduce the said fibrous body portion of the filler. This will be obvious from an inspection of Figure 5 of the drawings, and by reference to Figures 6 and 7 of the drawings, it will be further observed that the succeedin sets of rolls will have the flattening passes of a diminishing width to provide for bringing the wings of the fibrous body down to their predetermined size and form.

It will be observed in connection with the plan of manufacture suggested in Figures 5, 6, and 7 of the drawings, that one variation thereof would be to subject a mass of pulp or fibrous material (with core rods therein at intervals) to similar rolling operations which would reduce the mass to a plurality of integrall united filler members or units, as suggeste in Figure 8 of the drawings. According to this plan, it would only be necessary to sever the units along the shearing lines indicated by the dotted lines in said Figure 8 of the drawings.

It will also be understood that the fibrous body of the filler may beformed about any type of core. That is to say, the stiffening and reinforcing element which forms a ribshow other practical forms.

From the foregoing, it will be apparent that the distinctive feature of the present invention is a lathing fabric'having filler members or units of the character described, the said filler members or units being of a relatively great width, so as to preponderate in the ultimate structure, thus affording a very efficient plaster-keying base requiring the minimum quantity of plaster.

In short, it will be seen that the improved filler members or units, because of their width, make it possible to provide a substantial key base with relatively few filler elements which may be closely spaced to provide relatively narrow key openings therebetween. Thus, a fabric of the present type has the advantage of providing a plastlc-keying base upon which the plastic material may be readily applied Without Waste and held Without difliculty.

Without further description, it is thought that the many features and advantages of the invention will be readily apparent and it Will, of course, be understood that various changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit of the invention or scope of the appended claims.

I claim:

1. A lathing fabric consistingof flattened paper slat-s interwoven with metallic members, the said paper slats being reinforced with a metallic core.

2. A fabricated lathing structure including a filler slatconsisting of a flattened convoluted paperbody having a reinforcing core therein,

3. A fabricated lathing structure including a filler slat consisting of a flattened spirally convoluted paper body having a longitudinal metallic reinforcing core therein.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses.

ALEXANDER P. WHITE.
